Brief History

Shinpu castle (新府城) is located on the long cliff named Shitiriga Iwa facing Kamanasi river in Nirasaki city. Nirasaki city places on the northwest of Kofu city, on the way to Nagano prefecture. Shinpu Castle was built by Katsuyori Takeda (1546-1582), successor of Shingen Takeda (1521-1573) at 1581 as his new residence, but used in only several months.

Prior to succession of Takeda clan

Katsuyori was the fourth son of Shingen Takeda (1521-1573), a famous warlord of Kai province (Yamanashi prefecture). Katsuyori was fourth son and his mother (often said as princess Yufu or princess Koi) was stem from Suwa clan, a local lord of Suwa area (Nagano prefecture) which was extinguished by Shingen. Shingen married with the daughter of Suwa clan only to calm remaining Suwa people, thus at first Katsuyori was not considered to succeed Takeda clan

But in 1567, Yoshinobu Takeda (1538-1567), the eldest son of Shingen, was expelled and forced to die due to a conflict against Shingen concerning foreign policy against Imagawa clan, the parent's home of his wife. Also second and third son were unable to serve as a leader, thus Shingen had to choose Katsuyori as his successor. Under Shingen, Katsuyori well fought against Hojo clan or Tokugawa clan, and regarded as a brave general.

In 1573, during his campaign against ally of Ieyasu Tokugawa (1542-1616) and central ruler Nobunaga Oda (1534-1582), Shingen died in ill. Takeda clan chose Katsuyori as next leader, but it is said that Shingen stated in his will that 1) conceal his death in 3 years, 2) Katsuyori is a deputy leader and when Katuyori’s son (Nobukatsu) grow up, Katsuyori must transfer his position to Nobukatsu, 3) Katsuyori can not use the flag of Furin Kazan (a proverb by Sun Zi), a symbol of Shingen. This instruction might be made considering repellence of old generals who hated the son of former enemy to succeed Takeda clan, but this policy strictly limited authority of Katsuyori.

Expansion, defeat and struggle

Confronting expanding Oda clan and to establish his authority, after the succession Katsuyori aggressively attacked Oda and Tokugawa territory. In 1574 he occupied 16 castles of Oda clan in eastern Mino province (Gifu prefecture), and in 1575 he captured Takatenjin castle, where Shingen formerly attacked but could not occupy.

By these victories Takeda territory became its peak, but in June 1575, Katsuyori suffered a fatal defeat at the battle of Nagashino, facing 3,000 matchlock guns of Oda army. Takeda clan lost many experienced generals including Nobufusa Baba (Nobuharu, 1515-1575), Masahide Naito (Masatoyo, 1522-1575) and Masakage Yamagata (1529-1575), three of so called four excellent generals of Takeda clan at once.

After the battle, Katsuyori struggled to restore Takeda clan and keep his territory. He made friendship with Kenshin Uesugi (1530-1578), a warlord of Echigo province (Niigata prefecture) and former fatal rival of Shingen, and also married with a princess of Hojo clan, a warlord of Sagami province (Kanagawa prefecture), to make backside secure. Katsuyori also worked for a centralization of authority, nourish of commerce and strengthening of armies.

But in 1578 due to a sudden death of Kenshin, there occurred an internal conflict named "Otate no Ran" in Uesugi clan between two adopted son of Kenshin, Kagekatsu Uesugi (1556-1623), a son of Kenshin’s relative, and Kagetora Uesugi (1554-1579), born as a relative Hojo clan. 

If Kagetora wins Hojyo clan virtually dominate Uesugi clan and become too strong, thus to prevent this situation Katsuyori supported Kagekatsu. But due to this action Hojyo clan turned to the enemy of Katsuyori, and Takeda clan was surrounded by Oda, Tokugawa and Hojo clan only along with weakened Uesugi Clan.

Build of Shinpu castle

Under this situation, in 1581, Katsuyori thought necessity of more secure residence instead of small Tsutsujigasaki palace, to prevent invasion of Oda army from Shinano province (Nagano prefecture). Katsuyori chosen a cliff beside Fuefuki river in Nirasaki city, and started to build a new castle.

By the end of the year main areas were mostly completed. Katsuyori named this castle as Shinpu castle (new capital), and moved his residence with retainers from Tsutsujigasaki Palace to Shinpu. But strengthened military service and build of new castle became burden for local lords and evoked antipathy. Besides, Katsuyori could not rescue besieged Takagenjin Castle at Totomi province (western Shizuoka prefecture) in this year, and lost his confidence.

Shinpu castle was built on the hill of about 500 meter length and 200 meter width spreads to north and south direction. A square shaped central area locates at the top of the hill, and connecting space into the main gate was built at the west of central area. At the south of central area there were large flat area of secondary area and third area, and at the south edge of the castle there was a main gate and a large Umadashi, a round shaped fort guarded main gate. 

The north side of the castle is backward, but expected to be the front to enemy and a projection named "Degamae" was built. The purpose of this Degame is unknown, and someone says this was built as firing point but other people state this was merely a bank of water moat to keep the water.

Extinction of Takeda clan and afterward

Considering tough situation of Takeda clan, in early 1582, Kiso clan, a marriage relative of Taleda clan and guarded Kiso valley of Shinano province, turned to Oda clan. Utilizing this opportunity Nobunaga sent huge army lead by his eldest son Nobutada Oda (1557-1582) to extinct Takeda clan in February. At the same time, Tokugawa army and Hojo army advanced to Takeda territory from other directions.

Katsuyori intended to prevent Oda army in Shinano province (Nagano prefecture), but Takato castle, which was held by Morinobu Nishina (1557-1582), the younger brother of Katsuyori and only one castle resisted against Oda army, was captured in only one day. Looking at severe situation many generals and soldiers left Takeda army or hided themselves. In addition to this, in backward Nobukimi Anayama (1541-1582), a close relative of Katsuyori, betrayed to Tokugawa clan. 

Katsuyori could not keep the front and retreated to Shinpu castle in early March, but also could not hold here thus burned down this new castle and escaped to the eastward. Katsuyori at first attempted to escape to Iwadonoyama castle, the castle at eastern border of Kai province held by Oyamada clan. But Oyamada clan betrayed Katsuyori at final stage, thus Katsuyori advanced toward Tenmokusan mountain, where was a sacred place for Takeda clan. 

But before the mountain Katsuyori was captured by chasing Oda army at the place named Tano village, then fought with overwhelming Oda army and died there with his wife and his son Nobukatsu Takeda (1567-1582) in the middle of March. With this, Takeda clan collapsed in only one month and ended its history as a warlord over 400 years.

Oda clan once captured Kai province, but only three month after the fall of Takeda clan, Nobunaga himself died in incident of Honnoji at 1582, a coup d'etat by his general Mitsuhide Akechi (1528-1582). Both of Tokugawa clan and Hojo clan aimed at vacant Kai province, and Tokugawa army occupied Kofu town and besieged at the ruin of Shinpu castle. Facing with dominant Hojyo army came from Shinano province near Shinpu castlefor over 6 months, Tokugawa clan finally could kept Kai province. Ironically this was an originally planned usage of Shinpu castle by Katsuyori.
